' F. W. BREWSTER YARN SPLICING MACHINE Filed Aug. 23. 1922 IIIIHI'IIIIIIIlllllllllllIIIIIIIl Illlllllll HillllllllllllllllllI l EI EE! n 4 nunumnm|umnmmnmnunnim@ Zinnen/or surface of a woven fabric such, for inst-ance, as a cord tire fabric, without danger' of catching upon or displacing` the cords or filling. rlhe machine is, thereore, well adapted for use in repairing defective yarns or cords which may be found upon inspecting a woven fabric. In making such repair the defective portion of the yarn or cord is removed, the splicing machine is placed on top of the fabric while supported upon the inspecting table and is so positioned that the end of the fabric cord may be introduced into one of the twistei` heads while one end of the section of new cord is introduced into the other head, the ends of the cords introduced into the heads being held by the clips 26. By manipulation of the racks the heads may then be rotated to untwist the strands of the cords and then the strands separated and introduced into the strand holder 30. A pair of strands may then be twisted together and drawn taut between the heads and the splicing twist properly7 located at any desired point between the two heads, after which the ends of the spliced strands may be introduced into the holder S4 which prevents untwisting of the strands and also holds the splice in position while the other pairs of strands are successively twisted together and properly located. The racks may then be manipulated to retwist the spliced strands, the loose ends of the pairs of strands being removed from the holder 341-. The ends of the new section of yarn or cord may thus be quickly and conveniently spliced to the yarn or cord of the fabric and then the repaired yarn or cord drawn into its final position in the fabric.

While it is preferred to employ the speciic construction and arrangement cf parts in embodying` the invention in a portable machine adapted for use in repairing woven fabric it will be understood that this construction and rrangeinent is not essential l codified as found debest suit sir-able lor ,ce which the machine i4 Tfhat is claimed is:

l. A yarn splicing machine co iprising two opposed twister heads r ahl-l either direction, clips for holding :ne ends of the yarns passed through the twist r heads, a hoider baci; of the axial liie of constructed to hold ditferent L throughout its length the free ends of pairs of strands which are successively twisted together preparatory to retwisting the spliced strands, and a strand holder in front of the axial line of the heads for holding the untwisted strands leading from each head.

2. A yarn splicing machine comprising two opposed twister heads rotatable in either direction, a holder on one side of and parallel to the axial line of the heads constructed to hold at different points throughout its length the free ends of pairs of strands which are successively twisted together preparatory to rewisting the spliced strand, and a strand holder on the other side of and parallel to the axial line of the heads for holding the untwisted strands leading from each head.

3. A yarn splicing machine comprising two twister heads mounted in axial alignment, a pinion on each head, and a manual- .ly operable sliding rack geared to each pinion.

4. A portable yarn splicing machine comprising a base plate having an under surface below all parts carried by the plate and adapted to be placed by the operator on a woven fabric, two opposed twister heads rotatable manually in either direction mounted on the base, a strand holder for holding the untwisted strands mounted on the base and located above its bottom surface, and a holder constructed to hold at different points throughout its length the ends of the intertwisted pairs of strands also mounted on the base and located above its bottom surface.

5. A yarn splicing machine comprising two opposed twister heads mounted in axial alineinent, a pinion on each head, a shaft for each head provided with a gear engaging said pinion, a pinion on each shaft, and a manually operable sliding rack underlying and engaging each of said latter pinions.

6. A portable yarn splicing machine comprising a base plate adapted to be placed by the operator on a woven fabric, two opposed twister heads mounted in axial alinement on the upper side of the base plate, a pinion on each head, a shaft corresponding to each head provided with a gear engaging the pinion, a pinion on each shaft, and a sliding raclr underlying and engaging each of said latter pinions, the racks, gears and pinions all being 'ranged above the bottom surface of the plate.
